OS X

In my test environment I have installed all Citrix components (required) to access applications from remote locations.

Setup:

Citrix Access Gateway (VPX) Express

Self-Signed certificate. (Generated by CAG)

Citrix Webinterface (configured Services Site)

XenApp 6

This setup works for the following device OS’es:

Windows 7

IOS 5

Android 2.2

Only when trying to connect an OS X machine to the published application (via Citrix Receiver 11.4.3 It did not work.

After importing the self-signed certificate (crt/cer) to the keystore (login or system) I try to setup up a connection to the published application. After some time the connection failed with I receive the following error:

Citrix ICA SSL Error 61: You have not chosen to trust FQDN, the issuer of the server’s security certificate. Error number183

After trying some stuff, like importing it in different formats I eventually found the solution while doing the following steps:

Export your self-signed certificate to a convenient location.

Open Terminal and enter :

Enter:

Sudo su

Enter your admin user password

Enter:

mkdir /var/CTXScert

And:

mkdir /var/CTXScert/cacerts

Now copy your certificate to the just created folder, cp <your location> /var/CTXScert/cacerts/

quit Terminal.

Instantly after connecting again I was presented the Published application, the error had disappeared.
